SPECIFICATION forming part of Letters Eatent N 0. 594,953, dated December 7, 1897. Application filed December 31, 1896.' Serial No. 617,620. (No model.)

T0 all Lul/1,0m it may concern.-

Be it known that we, ELISHA F. HURT, of the city and county of New York, in the State of New York, and GARLAND N. WHISTLER, of Pompton, in the county of Passaic and State of New Jersey, have invented a new and useful Improvement in Separatore, of which the following is a specification.

-Our invention relates to improvements in machines for separating substances of different specific gravities in which the material being treated is projected into an upwardlyowing current of water.

The objects of our invention are to provide means for thoroughly separating the material being treated in a simple and eiective manner by first controlling the speed of the upwardly-flowing column or current of water; secondly, controlling the speed of projection of the material into the water; thirdly, by adjusting the height of the overflow-outlet, through which the material of lighter specic gravityis allowed to escapewith the upwardlyiiowin g current of water,and,fourthly, collecting and carrying away the material of heavier speciiic gravity.

A practical.embodiment of our invention is represented in the accompanying drawings, in whichl Figure l represents a transverse vertical section through the machine, the detachable receptacle for receiving the separated material being shown in end elevation; and Fig. 2 is a longitudinal vertical section through the machine.

The so-called controlling-chamber is denoted by A, and its bottom is of hopper shape, as shown at a, for directing the material which is of too great a specific gravity to be raised by the upwardly-flowing column of water downwardly into the receptacle to be hereinafter more fully described.

The means for admitting water into the controlling-chamber consists of a suitable inlet-pipe B, which enters the controlling-chamber A and there extends along bothends and the sides of the chamber. Along the under side of the water-inlet pipe B, within the chamber A, we provide suitable openings b, in the present instance through nipples, for

chamber A upwardly.

directing the water downwardly. The inletpipe B is provided with a suitable cock b eX- terior to the chamber A for regulating the amount of water supplied to the interior of the said chamber.

Uprising from the control-chamber A is a Vertical compartment or trunk C for directing the current of water from within the One side of the upright compartment C is provided with suitable outlet c for the upwardly-flowing current of water and the material of lighter specific gravity which is carried upward thereby,which outlet in the present instance is adjustable vertically and is in the formA of a suitable spout c. This spout is adjustable in the following manner: Each of the end walls of the compartment C is provided with a groove c2, extending from its top downwardly to within a short distancefrom its bottom, and within these grooves are fitted to slide cross-slats c3. It will be seen that by inserting a proper number of cross-slats c3 beneath the spout c the said spout may be adjusted to any desired height within the compartment C.

An adjustable chute D is located in position to direct the material to beseparated into the upwardly-flowing current of water within the trunk C. The lower end of the said chute is hinged, as shown at d, to the trunk C, and it is provided with a suitable elastic water-tight joint with the said trunk C, which joint in the present instance consists of two sheets of rubber 0r other elastic material CZ' d2, which are fastened at their ends to the chute D and to the trunk C. The chute D is made adj ustable to any desired inclination by means of suitable sector-racks E, hinged at their'forward ends at e to the trunk C, their teeth e' being engaged by a suitable spring-actuated pawl e2 on the chute D. The free or upper end of said chute is provided with a suitable hopper D for the reception of the material to be treated.

A gate F for controlling the speed of the .upwardly-flowing column of water for more eifectually separating the material being treated is located within the trunk C and is hinged along its upper edge to the lower edge of the chute D, as shown at f. The gate may IOO be swung back and forth by any suitable means. In the present instance we have shown a rocking lever G, pivoted at g and having a pin-and-slot connection at its inner end with the gate F, as shown at g', and having a suitable operating-han die g2 without the compartment C.

A water-tight receptacle H for receiving the separated material of heavier specific gravity is located beneath the control-chamber A and communicates therewith through a suitable connecting-pipe I, which is provided with a valve 'L'. The receptacle H is shown in the present instance as being provided with suitable traction-wheels h, running upon a track 71,', for facilitating the removal of the said receptacle.

A suitable support J is provided for supporting the controlling-chamber, connectingpipe, trunk, and chute at the proper height above the level of the ground, so that the receptacle H may be readily moved into position beneath the connecting-pipe I and also moved away for conveying the separated material to any point desired.

In operation the several parts are adjusted for use in connection with the particular material to be treated by properly adjusting the angle of the inclination of the chute D and the height of the outlet c in the trunk C, and the admission of water through the pipe B is properly controlled by the valve b'. The gate F is also properly adjusted to obtain the proper speed in the upiiowing column of water for effectually separating the material as it enters the trunk C from the chute D. The water will first fill the controlling-chamber A and receptacle H. It will then flow upwardly in the trunk C and chute D until the level of the water reaches the height of the outlet c in the trunk C. As the material to be separated is projected through the chute D into the trunk C the substances of lighter specific gravity are carried upwardly by the current of water and out through the outlet c. The heavier substances are allowed to fall into the control-chamber A, and from there are positively directed down into the receptacle H by the downwardly-projected jets Z) in the inletpipe B. Then the receptacle H has received the proper amount of separated material, the valve t' is closed and the receptacle H is removed, and another receptacle may be placed in position, or the same receptacle H may be returned after having its contained material removed. The rest of the machine may be still allowed to operate, if so desired, and allow the material of heavier specific gravity to accumulate in the lower part of the controlchamber A until the valve t' is opened, or the balance of the machine may be stopped until it is desired to start it again.

It will be seen that the separator as above described may be used for separating any two substances of different specific gravities or for the purpose of separating a heavy substance from several lighter ones-such, for example, as separating ore from ore-pulp.

Vhat we claim isl. A machine for separating substances of different specific gravities, comprising a control-chamber, water-feeding means therefor, a receptacle communicating with the controlchamber for receiving the material of heavier specific gravity, a trunk or compartment uprising from the control-chamber and having a suitable outlet for the upwardly-flowing current of water and substances of lighter specifc gravity, a chute for feeding the material to be separated, hinged to the said trunk, and means for adjusting the inclination of the chute, substantially as set forth. i

In a separator, a controlchamber, a trunk uprising therefrom and provided with a suitable outlet for the upwardly-flowing current of water and substances of lighter speciiic gravity, a chute for directing the material to be operated upon into the trunk, means for feeding water under head or pressure into the control-chamber, a gate hinged at the discharge end of the chute within the trunk and means for adjusting the free lower end of the gate in different positions across the interior of the trunk to adjust the action of the separator to materials of varying specific gravties with precision, substantially as set forth.

3. In a separator, a control-chamber provided With 'converging inclined bottom Walls, a trunk uprising from the chamber and provided with a suitable outlet for the upwardlyiiowing current of water and substances of lighter specific gravity, a chute for .directing the material to be operated upon into the trunk, means for controlling the passage of` the material into and the passage of the Water from the control-chamber and a water-feed pipe Within the control-chamber provided with downwardly-directed discharge-openings at intervals above the inclined bottom walls for causing the currents of water to impinge the said inclined walls and material thereon to prevent clogging, substantially as set forth. j
